Java

JavaScript is single-threaded, yet it powers the world's most complex real-time interfaces. Behind that magic lies the event loop; a mechanism that is often misunderstood, feared, or simply ignored until a performance bottleneck brings your app to a screeching halt. This May, we’re celebrating Star Wars month by traveling to the core of the JS galaxy to bridge the gap between "it just works" and "I know why it works". Join us for an evening of live-coding and deep dives. Whether you’re a Padawan or a Jedi Master, come learn how to make the runtime work for you, not against you. **Agenda** * 17:30 – **Doors open** * 18:30 - 18:50 – **Settling in & Intro** * 18:50 - 20:30 – **Talks and pizza** * 20:30 – **Networking** **Explore the detailed agenda and speaker info: [https://zurichjs.com/events/may-2026](https://zurichjs.com/events/may-2026/?utm_source=zurichjs&utm_medium=meetup&utm_campaign=meetup_track)** **About the organizers** * **[Bogdan Ilie](https://www.linkedin.com/in/ilie-bogdan/)** is a user advocate.

Let's meet at the CNC meetup on Thursday, May 21st, 2026, at 15:00 CET. **Location:** VSHNtower, 8th floor, Neugasse 10, 8005 Zürich **Agenda:** Would you like to speak at this event? Contact us at [https://cnc-meetup.ch](https://cnc-meetup.ch)! Guidelines: * All sessions are held in English. * No product or sales pitches are allowed. * All projects showcased should be open source. * We cannot cover travel costs, but we welcome speakers from other regions. * We're seeking more diversity among our speakers: underrepresented groups are welcome! 14:30 – Door Opening 15:00 – Welcome, Intro, & Announcements 15:05 – Kuberik: Safe, Hands-Off Deployments for Kubernetes (Luka Rumora) 15:35 – 5 minutes pause 15:40 – Kubernetes Without the Operator: A Minecraft Panel with Rust and kube-rs (Hadi Cherkaoui, CM Informatik AG) 16:10 – 5 minutes pause 16:15 – Vibe Code Survival Guide for Open-Source (Vadim Bauer, 8gears) 16:45 – 5 minutes pause 16:50 - Writing a Kubernetes Cluster Autoscaler Provider with externalgrpc (Marco De Luca, VSHN) 17:20 – Final words, networking & apéro Kuberik: Safe, Hands-Off Deployments for Kubernetes (Luka Rumora) Most teams deploying to Kubernetes end up in one of two places: either GitOps that stops at applying manifests, or brittle CI pipelines full of bash and glue. Both fall short of true end-to-end delivery. The ideal is well known—canaries, health checks, smoke tests, promotions, rollback—but Kubernetes lacks a native, reusable way to compose these without reinventing everything. Existing tools solve pieces (Argo Rollouts, Flagger, Kargo), but not the whole pipeline. Kuberik fills that gap: it orchestrates the full journey from release to production—detecting, gating, rolling out, verifying, and promoting—using opinionated, pluggable Kubernetes resources that integrate with existing GitOps setups. Luka is a Lead SRE with 10 years of experience building platform infrastructure and internal developer tooling, always with the same focus: systems that are robust, easy to maintain, and a pleasure to use. Over the years, he has watched the delivery tooling landscape change, from Jenkins to GitLab CI to Drone to GitHub Actions, yet the fundamental approach to CD has stayed the same: step-based pipelines with the same challenges they had a decade ago. He built Kuberik because he believes we can do better. Kubernetes Without the Operator: A Minecraft Panel with Rust and kube-rs (Hadi Cherkaoui, CM Informatik AG) Anvil is a Kubernetes-native Minecraft server panel written in Rust. It creates one StatefulSet, PVC, and Service per server through direct kube-rs calls, with no CRD and no controller. The Kubernetes API itself is the runtime state store; every user action is a direct API call. This 20-minute talk argues that the operator pattern is sometimes the wrong tool. Controllers earn their complexity when there's autonomous state to reconcile. They become a ceremony when there isn't. Anvil is a worked example of the imperative alternative, running on a home lab k0s cluster. Hadi Cherkaoui is a 17-year-old EFZ Plattformentwickler apprentice at CM Informatik AG in Schwerzenbach, ZH. He works daily with k0s and FluxCD, and is interested in Kubernetes, Rust, infrastructure automation, and homelab projects. Vibe Code Survival Guide for Open-Source (Vadim Bauer, Container-Registry.ch) Vibe code is flooding open-source projects with an ever-growing volume of pull requests and ideas. Banning AI contributions isn't the answer, yet it is difficult to resist. How can open source projects survive and keep progressing despite the pressure? This talk covers the project playbook we're building in CNCF Harbor and Harbor Satellite: defining a clear project direction so contributors, human or AI-assisted, know what's in scope before they contribute. Setting explicit acceptance criteria and guardrails. Using AI on the maintainer side to triage, review, and filter the growing volume of contributions. Deciding as a project where your boundaries are, what's core, what's an extension, and what's out of scope, so you stop drowning in well-intentioned feature PRs that slowly erode coherence. We share what works, what fails, and how we are rethinking open-source, contributions, community, and project Vadim Bauer is a Container Silverback with over a decade of experience in running containers in production. As a maintainer of the CNCF project Harbor, he focuses on extending the boundaries of OCI artifact management, adoption, and developer experience. At 8gears, Vadim helps cloud providers, ISVs, and enterprises adopt Harbor and use OCI capabilities. Writing a Kubernetes Cluster Autoscaler Provider with externalgrpc (Marco De Luca, VSHN) The Kubernetes Cluster Autoscaler decides when to scale, but it doesn't know how to create a VM. That's the cloud provider's job, and the upstream tree covers mostly big clouds. With externalgrpc, you can plug virtually any cloud into the autoscaler over gRPC. This talk first looks at how the Cluster Autoscaler works under the hood and where the cloud provider fits in. Then we walk through implementing one for a Swiss IaaS provider as an out-of-tree gRPC service: the design choices, the parts of the contract that matter, and the gotchas you only find by reading the autoscaler source. By the end, you'll know how to attach autoscaling to a cloud that isn't on the upstream list. Marco De Luca is a software/infrastructure engineer at VSHN AG. He spends most of his time on Kubernetes platforms, developer tooling, and making sure things don't break at 3 AM. At mdnix.io, he writes about infrastructure, Linux, Kubernetes, and the things he builds along the way. When he's not behind a terminal, he's somewhere in the Alps with his camera or having a private jam session with his guitar. The event will be recorded and made available on VSHN's YouTube channel: [https://vshn.tv](https://vshn.tv). Subscribe to stay notified of updates. We expect all participants to abide by VSHN's Conference Code of Conduct: [https://www.vshn.ch/en/code-of-conduct/](https://www.vshn.ch/en/code-of-conduct/) If you would like to share your cloud-native projects at the CNC Switzerland meetup events or sponsor future events, just send us your talk suggestion here: https://cnc-meetup.ch.

Hares are Big Top & Spermalbad. Come and join us! **Where**: Zürich Hegibachplatz / Minervastrasse, Forchstrasse 95, 8032 Zürich. Look for English speakers wearing running gear. **When:** We'll meet at 6:50 pm to start at 7:00 pm. There's a charge of CHF 5 for participating, which covers all you can drink beer/cider (and non-alcoholic alternatives) plus snacks afterwards. **All Welcome:** If you are new, curious, and want to get out of the house, stretch your legs, talk shit, enjoy a drink, and hopefully a laugh, then here's what you need to know: • We are a social running/walking group. Physical fitness is not required, but a sense of humour is helpful. • The aim is to find the '*Beer Stop*' at the end of the '*trail*' and to have fun. • 'True Trail' is 4-7 km. Some will go less (especially those walking or walk/running), and some over-achieving fast runners will go further. • The '*Hare*', who (along with the location) changes with each event, cleverly lays the trail, marking it with chalk, flour, and/or sawdust so that everyone reaches the end more or less at the same time. • There is always a place to deposit your bag, and sometimes a place to change. • **After Trail**, we group in the '*Circle*' for \~30-40 minutes for drinks, snacks, songs, and fun. This is typically outside, so leave something warm in your bag in winter (and bring a flashlight when it's dark). If you don't want to stand around drinking afterwards, you can head home. We occasionally all go to a restaurant afterwards. **Why bother leaving your warm & dry sofa?** If you enjoy getting outside, being around people, and doing something a bit different, you will probably enjoy hashing. Exercise is important, and this is probably the least boring way to get it. 'Hashing' and the idea of some physical activity to work up a thirst, have been around for almost 90 years and there are groups (*Hashes*) in most major cities. Its humor and 'traditions' can be explored on the internet - **or you can just come along and find out.** *See you there.* We are of many nationalities, all ages, full of misfits and idiots (at least there is no one taking themselves seriously!) and always welcome newbies 'Virgin Hashers' and visitors from other groups.

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

Model Context Protocol (MCP) is emerging as a standard way for AI models to securely interact with external tools and systems. This session provides a practical deep dive into MCP architecture, core concepts, and real-world integration patterns. We will explore how MCP enables structured tool calling, improves interoperability, and simplifies AI integration in existing applications. The talk will include examples of connecting AI models with APIs, databases, and enterprise systems, with a focus on how developers can adopt MCP in Java-based environments. **Note**: This is a hybrid in-person/online event. Food and social for those in the OCI training room starts at 6:00pm. Presentation starts at 6:30pm for those online and in the training room.
